Boeing has issued two SLs specific to ranges of aircraft that had quality issues with production delivery installed springs. Boeing aware, FTD 737NG FTD 32 03004 refers. Airport authorities informed, spring replaced. DR 611750477ĭuring walk around, RH MLG FWD up lock spring found missing. The strut was replaced and all door operation and indications checked normal as per AMM.īOEING 737 838–ATA 3210 MAIN LANDING GEAR–SPRING–Part Departed Aircraft.
In consultation with Bombardier, it was established that forces required to operate strut from fully extended position to fully compress were well below the AMM figures (30.8 37.5 lbs against required figures ranging from 36 58 to 55 86 lbs. The passenger door handle over centre gas strut had weakened to the point where the door could be ‘unlocked’ by applying very light pressure to the handle. QRH checklist followed, requiring the aircraft to be depressurised.
Passenger door warning appeared at 5000′. OEM is still working on a permanent solution for the poor reliability of the NAPRSOV.ĭE HAVILLAND DHC8 102–ATA 5270 DOOR WARNING SYSTEM–GAS STRUT–Less force required to operate. These findings are in line with the known world fleet findings. NAPRSOV found seized with the disk ring jammed in the ring to valve housing. Shop report for NAPRSOV confirms primary finding of a broken and worn butterfly valve assy disc ring. Subsequent operational test of both bleeds carried out satisfactory. #1 and #2 engine NAPRSOV replaced per AMM Task 36 11 03 400 XX. Fleet technical suggested NAPRSOV at fault. During course of troubleshooting, #1 engine NAPRSOV butterfly sealing ring found dislodged. Therefore, flight crew performed an air return to departing base due to loss of both bleeds. ‘Bleed 2 Fail’ EICAS message appeared on landing. Anti-skid functional checks carried out IAW AMM.ĮMBRAER ERJ190100–ATA 3610 PNEUMATIC DISTRIBUTION SYSTEM–NAPRSOV–Internally leaking. Defect confirmed to be rectified through extinguished annunciator on CWP. Wire repaired by crimping of new contact pins IAW SAAB 340 AWM CH 20 20. Defect was traced to a broken wire at LH I/B MLG wheels speed transducer. Crew made a PAN call and the landing was made without incident. Annunciator illuminated once again when gears were extended. With gears up, warning was no longer presented. With LGs selected down, anti-skid CWP annunciator illuminated. SAAB 340 B–ATA 3241 BRAKE ANTI-SKID SECTION–Anti-skid release lights on–Wire damaged. Root cause behind detachment of light cover (track plates) plates could not be established. Light plate panel reassembled and installed onto pedestal IAW 33 13 XX and 27 51 XX.
Crew discussion confirmed track plates on cockpit flap lever panel assy had fallen out and jammed lever. Object shifted after third attempt, thereafter normal approach and landing conducted. DR 611750453Ĭrew unable to extend slats due to plastic object stuck in flap track (module).
